The internet has made it very easy to find a virtual safety bubble, which promotes self-acceptance over personal growth. Where you’ll always find something to agree with you on want to agree with. Where you’ll find that plenty of people, no matter what your stance, proclaiming how the opposition is just a lie. This goes for anything, everything
Like any cards, it can be used the right way or he wrong way. If you position is true, and noone in real life agrees with you, except some do online, then the internet is good at that moment. If your position is false, and people agree with you online, then it is bad at that moment.
